−2 / j +7=−12 the slash is a fraction with the -2 and j i need this simplified asap

j = 2/19

Step-by-step explanation:

Step 1: Subtract 7 on both sides

-2/j = -19

Step 2: Multiply j on both sides

-2 = -19j

Step 3: Divide both sides by -19

2/19 = j

If the question is -2/(j + 7) = 12:

Step 1: Multiply both sides by j + 7

-2 = 12(j + 7)

Step 2: Distribute

-2 = 12j + 84

Step 3: Subtract 84 on both sides

-86 = 12j

Step 4: Divide 12 on both sides

j = -43/6 = -7.167

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere

f(x) = y

f(-3) = -5
